Where do you usually need to check if the engine shakes seriously?

After starting the engine, check whether the engine fault warning light is off. If the warning light does not turn off, check the cause and part of the fault according to the fault code; if the warning light is turned off, determine the rapid matching setting.Check whether the cylinder is missing, whether the cylinder line is correct, and whether the plug-in connection is reliable. Check whether the idle execution device is normal.

The engine will shake more than normal, and may even not start at once. Therefore, when the vehicle shakes, the throttle valve and fuel injector should be checked first. If you find that the throttle valve is too dirty or the fuel nozzle accumulates too much carbon, it should be cleaned in time.

Engine lack of cylinder, engine lack of cylinder mainly refers to one or more cylinders in the engine not working properly, which is manifested as: the exhaust gas flow discharged by the car has obvious intervals, and the exhaust pipe shakes greatly, which can obviously feel the shaking of the engine, sometimes accompanied by a stuttling sound.

Too much carbon accumulation If the carbon accumulation in the engine cylinder is serious, it will makeThe case of spark plug blockage and valve blockage directly causes the car to shake when idling. If the acceleration ability of the car is not as good as before and the shaking is very long-lasting, you can consider cleaning the inside of the engine cylinder.

What's wrong with car engine shaking

Engine parts aging. Car jitter is also related to the aging of engine parts. At this time, if there is a problem with the engine parts, these vibrations will be transmitted to the steering wheel and the cab, causing jitter when idling. Solution: Replace auto parts. The engine has serious carbonization.

The reasons for engine shaking are as follows: engine cylinder deficiency: engine cylinder deficiency mainly refers to the abnormal operation of one or more cylinders of the engine, throughIt is often manifested as an obvious intermittent exhaust flow in the car, and the exhaust pipe shakes violently, so you can obviously feel the engine shaking, sometimes accompanied by a sudden noise.

The throttle valve is too dirty or the fuel injector has too much carbon, and the ignition system is a problem. For the problem of the ignition system, it is necessary to check the working condition of the spark plug, high-voltage conductor and ignition coil. The poor operation of the ignition system and the poor condition of the spark plug jumping will also lead to such failures. Too much carbon needs to be cleaned up in time.

The reasons for the shaking of the car engine are as follows: engine cold start: After a cold car is parked outdoors for a long time, the engine will vibrate violently and then make noise. Because at this time, the lubricating oil basically flows to the bottom shell, the oil pressure cannot be established immediately, and the rattling sound is not enough when starting.

What is the reason for the engine shaking when the car starts?

Air filter is dirty: The air filter is designed to protect the engine and reduce wear. It is generally replaced around 10,000 kilometers. If the replacement is not timely, insufficient air intake will lead to low idle speed and make the engine shake. As long as the filter element is replaced, it can be solved.

Dirty air filter: The air filter is designed to protect the engine and reduce wear. Generally, it is replaced at about 10,000 kilometers. If the replacement is not timely, it will cause low idle speed due to insufficient air intake, causing the engine to shake. As long as the filter element is replaced, it can be solved.

The reasons for engine shaking are as follows: engine cylinder deficiency: engine cylinder deficiency mainly refers to the abnormal operation of one or more cylinders of the engine, which is usually manifested as obvious intermittent waste of the car.Airflow, the exhaust pipe shakes violently, so you can obviously feel the engine shaking, sometimes accompanied by a sudden noise.

What is the reason for the engine shaking when the car starts

Engine foot shakes Automatic transmission The car was on the forward gear but shook fiercely before it started.As a result, it is likely that the engine foot is faulty. In the process of using the car, the wear rate of the engine foot is much higher than that of other parts. After a long time or the engine foot has certain quality defects, deformation and other problems may occur.

The engine has serious carbon accumulation. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

Dirty air filter: The air filter is designed to protect the engine and reduce wear. Generally, it is replaced at about 10,000 kilometers. If the replacement is not timely, it will cause low idle speed due to insufficient air intake, causing the engine to shake. As long as the filter element is replaced, it can be solved.

Injector blockage: Electric injector injector is a key part of automobile injector, with a long service life, up to hundreds of thousands of kilometers. But byThe nozzle hole of the nozzle is blocked in gasoline, so the nozzle volume of each nozzle is inconsistent, resulting in inconsistent operation of each cylinder, resulting in engine shaking. The solution is to disassemble and clean it.

The engine shakes when the car starts

1. This is a normal phenomenon. Almost all cars will shake when starting the engine. When starting the engine, the engine does not work smoothly, and some jitter will occur in the engine. Some engines with poor smooth operation will also keep shaking after starting, which is a normal phenomenon.

2. The engine carbon accumulation is serious. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

3. The most common cause of car shaking is that the throttle valve is too dirty or the fuel nozzle accumulates too much carbon.

4. Cold start jitter First of all, start from the cold start. The main reason for the cold start body shake is insufficient fuel combustion, resulting in insufficient power of the car. The ignition energy is low. When starting, especially when the temperature of fuel and lubricating oil is low, more oil is needed to meet the power.
